What does the time constant (τ) measure in an RC circuit?
The total voltage
The response time to a step input
The current flowing
The resistance value
After how many time constants does an RC circuit reach approximately 63.2% of its final value?
3τ
2τ

1τ
What happens to the current during the charging process of a capacitor?
It stops
It remains constant
It decreases
It increases
In a discharging RC circuit, what happens to the capacitor voltage over time?
It increases
It decreases
It stays the same
It fluctuates
What is the formula for calculating the time constant (τ) in an RC circuit?
τ = R * C
τ = R + C
τ = R / C
τ = R - C
